Hanford tank farm workers met Wednesday night in Richland to discuss chemical vapors. There have been 38 exposures since March. Workers call it an epidemic. With little they say being done by their bosses, they're banding together looking for solutions to stay safe.

Exposure to potentially harmful chemical vapors sent 26 workers at the Hanford Site to a Richland hospital or an on-site medical clinic in the two-week period starting March 19. For the first time, two of those workers talk on camera about their experience.

Hanford contractor Washington River Protection Solutions says all the workers have been cleared by doctors. The company says it is taking steps to prevent employees from being exposed to chemical vapors.

Three employees of a Hanford contractor were given medical evaluations after being exposed to vapors in a tank farm. Workers had been evacuated from a farm Tuesday after several reported smelling chemical vapors.

The Department of Energy says the Waste Sampling and Characterization Facility at the Hanford site will close within a year. According to DOE, using offsite labs to analyze waste samples will save around $12 million a year.
